Concept:Vulcanization is the heating of natural rubber with a substance that forms cross-links between rubber polymer chains, making the rubber stronger and more elastic.
Explanation:The common agent used for vulcanization is sulphur, also known as sulfur (
S).
When rubber is heated with sulphur, the sulphur atoms bond with the double bonds in the rubber molecules.
These new cross-links give the rubber better strength, elasticity, and resistance to heat and wear.
Chlorine and hydrogen peroxide are not used for this purpose.
Tetraoxosulphate(vi) acid is an acid and does not act as a vulcanizing agent for rubber.
Answer:C. Sulphur
